# Pillar Synthesis

This skill transforms raw evidence objects into structured insights for a single research pillar.

## Prerequisites

- Evidence gate passed (≥5 evidence objects for this pillar)
- Evidence objects in `02-evidence/<pillar>/`

## Workflow

Use TodoWrite to track these mandatory steps:

<required>
1. Load all evidence objects for the pillar
2. Identify patterns and themes
3. Resolve or document contradictions
4. Extract key insights
5. Generate synthesis document
6. Link insights to evidence IDs
</required>

### Step 1: Load Evidence

Read all `EV-<pillar>-*.yaml` files from `02-evidence/<pillar>/`.

For each evidence object, extract:
- Claim
- Confidence
- Assumptions
- Tags

Build a working set of all claims.

### Step 2: Identify Patterns

Group evidence by theme:
- What claims cluster together?
- What topics have multiple evidence points?
- What themes emerge across sources?

**Pattern identification:**
```
Theme: Pricing
├── EV-market-pricing-smb-wtp (0.75) - SMB WTP $29
├── EV-market-pricing-enterprise-wtp (0.80) - Enterprise WTP $99
└── EV-competitors-pricing-benchmark (0.70) - Market avg $45

Insight: Pricing flexibility needed for multi-segment
```

### Step 3: Handle Contradictions

For contradictory evidence:

1. **Note the contradiction explicitly**
2. **Assess confidence delta** - Higher confidence wins if large gap
3. **Check recency** - More recent may supersede older
4. **Check authority** - More authoritative source wins
5. **If unresolved** - Document both, flag for decision-making

```markdown
### Contradiction: User Segment Priority

**EV-users-segment-power-users** (0.70): Power users drive retention
**EV-users-segment-casual** (0.65): Casual users drive growth

**Resolution:** Unresolved. Both valid for different goals.
**Recommendation:** Requires explicit decision (DEC-*)
```

### Step 4: Extract Key Insights

For each theme, formulate 1-3 key insights:

**Insight structure:**
- **Observation:** What the evidence shows
- **Im
